I56600K, GTX980Ti, 8gb of ram, no SSD for me, ultra settings without any problems for 2v2 where I play.
8gb of ram is fine for CoH2, in fact it should be enough for all games that don't have obvious memory leaks.
In CoH2 case, its more CPU demanding then anything.
Well then how you explain that I also run the game on max settings, with the AA trick, on i5-2500k and gtx760 with 16gb of ram and ssd. I also had really long loading times until I started to defrag after every patch and eventually bought ssd when I became tired with that chore. Its not cpu demanding that much, 2500k, that is a 4,5 year old cpu, doesnt even stress in coh2.
I also could play the game on 8gb but only if I turned everything off in the background including browser, media player, voip, celo and so on. This makes game much less enjoyable.
